# THE VERSION IS THE CLI'S, READ FROM IT. This was the literal "1.0.0", hardcoded when the
# operator was a script in a repo and never touched again — so `unoverse help` announced
# v1.0.0 while the published CLI was on 0.1.95, and the one number a developer uses to say
# which version they are running was wrong by two hundred releases.
#
# THE MONOREPO PATH IS TRIED FIRST, and the order matters. Two levels up from scripts/lib
# is the PLATFORM's package.json, which is genuinely 1.0.0 — so looking there first found a
# real version that was not this CLI's, and reported it confidently. packages/cli exists
# only in the monorepo; published, that path misses and the package's own is two levels up.
